Managed to pick up a copy of this camera, handle used, here in Phnom Penh, several months ago and what a great purchase that was. After using it for a few months and making some decent images with it I now feel in a position to give a working photographers opinion on it.
As mainly a still image maker I am less interested in this cameras Video abilities, even though they are pretty darned good.
The FUJIFILM X-T3 features a newly-developed back-illuminated X-Trans CMOS sensor, the fourth generation to feature in the X Series. It has a resolution of 26.1MP. The sensor uses a unique color filter array, synonymous to X-Trans CMOS sensors, to control moiré and false color without the use of an optical low-pass filter. Its back-illuminated structure enhances image quality while maintaining a high S/N ratio. Furthermore, ISO160, previously available only as extended ISO, is now part of the normal ISO range, allowing you to achieve incredibly clean, noise free images.

The FUJIFILM X-T3’s sensor has increased the phase detection AF area to the entire frame with 2.16M phase detection pixels. The low-light AF sensitivity has also been extended enabling high-speed AF in even lower light conditions. I have found the AF to be a big improvement over that in my XT2 even though that was no slouch.
The performance of face-detection AF on a moving person has been doubled and works very well IMO. The eye-detection AF works in AF-C mode, maintaining accurate focus-tracking with portraits.
Continuous shooting of 11fps with the mechanical shutter no longer requires the optional vertical grip. I have the vertical grip and it not only give high speed shooting but extra battery life which was always a complaint with Fuji Cameras.
The FUJIFILM X-T3 offers 16 Film Simulation modes so that you can match your true photographic intention in a similar way to how photographers used to choose purpose-specific photographic films. I am not a photogrpher that feels the need to use RAW (all the time) as I find the way this (and other Fuji offerings) produces out of the camera JPEGs to be astounding and saves me numerous hours in post processing.
One of the main things that attracted me to the Fujifilm system is the way that it manages colour and the ability to bracket using 3 different film silmulations, including monochrome. I can adjust each basic film simulation to the way I want it to be (in the camera) and save that as a custom setting. (only works with JPEGs). Very easy to do.





Fuji has always come into some critism about its AF speed. I have never really found it to be a problem even on my X Pro 1, (much better after they upgraded the firmware). The XT2 and XT3 are IMO good and very good and are able to meet all situations. There are many AF phase detection points that are now easily seletable via the small joy stick on the rear of the body. Phase detection AF is the AF system used in viewfinder shooting on mirrorless and DSLR cameras. It works by splitting the light entering the lens into two so that it forms two images. … Phase detection AF enables autofocus be established swiftly, since the camera knows exactly how much and in which direction to move the focusing lens.
Weight, even with the extra handgrip and batteries is comfortable and manageable. The camera feel solid and well made. Nowhere near as heavy as my Canon 1D MkIV which makes it great for use as a daily carry around camera.
